A series of pictures – or a carousel,… Never before has an Instagram caption been so loaded. On Tuesday afternoon, the Kensington Palace account posted this seemingly innocuous announcement: “Welcome to Instagram, @SussexRoyal! Follow @SussexRoyal for more on the work of The Duke and Duchess of Sussex. Follow @KensingtonRoyal for more on the work of The Duke and Duchess of Cambridge.” And lo, the division of the households of Sussex and Cambridge was complete. We knew they would no longer share a team of advisers, aides and press officers. But a split of their Instagram accounts sealed the deal. @SussexRoyal entered the social media stratosphere with a post which was, frankly, peak Harry and Meghan.
